A MESSAGE TO ALL OUR FANS

During yesterday’s show in Boise, Deryck sustained another back injury and we have been forced to cancel the remaining Warped Tour dates and the Canadian run that was to follow.

We hate canceling shows, but Deryck’s well being is our top priority and the best thing right now is to give him time to heal.Thank you for your understanding. We wish Deryck a quick recovery and look forward to getting back out on the road.
